Package com.epicentric.metrics Description

Supports the monitoring and collecting of data such as PortalBean page hits, unique user sessions, and other usage patterns per page, PortalBean, PortalBean view, user, etc. As shipped, a Vignette Portal installation collects and archives concurrent usage, site, page, domain, general PortalBean, and other metrics. In addition, the metrics API can be used to monitor, collect, and archive any custom data of interest to an installation.

Vignette Portal accumulates both custom and Vignette Portal-defined metrics in a log. At a particular (configurable) interval, the log data is archived into relational database tables, and the log is emptied. All Vignette Portal and custom metrics tables can be queried through Vignette Application Builder, custom metrics PortalBeans, or any external reporting mechanism. In addition, the Vignette Portal-defined metrics data can be viewed using the Vignette Portal administrative pages.

The metrics API uses the Managed Bean design pattern of the Java Management Extensions (JMX) specification. Each metric is a Managed Bean (MBean) implementation. Two Vignette Portal classes provide support for the development of custom metrics: CustomMBeanFactory and CustomMonitor.

For further discussion of the metrics API and an example of a custom metric, see Vignette Portal Developer's Guide available from Vignette Global Marketplace, http://global.vignette.com.
